UC1 General FAQ



What is your Channel Strip plug-in based on?

With the introduction of SSL 360 v1.4 there are now 2 flavours of Channel Strip available for UC-1. The SSL Native Channel Strip 2 was developed from our digital modelling of the XL9000K series console EQ and Dynamics curves. The Super Analogue circuits of the XL9000K are renowned for their extended frequency bandwidth, minimal phase shift, low-distortion and all-round punchy sound.

SSL Native 4K B offers the sound of the legendary SL 4000 B-series console in your DAW. Expertly modelled, the 4K B plug-in is an authentic emulation full of tone, punch and rich non-linear analogue character – making it the perfect companion the cleaner 9K-inspired Channel Strip 2 plug-in.


Does UC1 work with my third-party SSL Plug-ins?

No. UC1, the Plug-in Mixer and the 360°enabled Channel Strips & Bus Compressor 2 are designed as a connected suite of hardware and software tightly integrated by the SSL 360 app. However, we are planning to add new ‘flavours’ of Channel Strips plug-ins in the future to further expand the range. 


Do I need to have UC1 connected to use the Plug-in Mixer?

No! You can use the plug-ins and Plug-in Mixer without the UC1 hardware attached!

SOLO isn't working?

VST3 DAWs with Follow Solo and Mute

With the introduction of SSL 360 v1.4 some VST3 DAWs now have the SOLO and CUT buttons in 4K B and Channel Strip 2 control the DAW track’s Solo and Mute (‘Follow Solo and Mute’). See the table below for DAW specific implementation of this feature.


DAWs that do not support Follow Solo and Mute

For non-VST3 DAWs and Cubase the SOLO button on 4K B, Channel Strip 2, Plugin Mixer and UC1 works by cutting the output of all other channel strips plug-ins in the DAW session. It doesn't directly control your DAW's solos. The best way to use the SOLO feature is to place a channel strip onto all the tracks in your DAW session, ensuring that  the SOLO SAFE button is engaged on plug-ins that are inserted on Auxes/Busses/Sub Groups. This will then enable you to use SOLO as intended.

AU/VST Channel Strip 2 and Bus Compressor 2 plug-ins are not showing up on UC1

In Cubase, Studio One, Live, and REAPER AU and VST plug-ins are not supported by the plug-in mixer. 

Use the provided VST3 plug-in formats, as these provide the SSL 360° Plug-in Mixer with special hooks to synchronise the DAW track name and track number. See this FAQ (Studio One and SSL Native) for information about using SSL VST3 plugins in Studio One on an M1/M2 Mac. The above does not apply for Logic, whereby AUs are supported in the Plug-in Mixer.
